Application filed April 13, 1914. Serial NO. 831,593.

To all 'wlw'm'z't may concern j Be it known that 1, JOHN SHARP, asubject of the King of Great Britain, and res1- dent of 26 Bordenstreet, in the city of Toronto, county of York, Province of Ontario, inthe Dominion of Canada, have 1nventecl certain new and usefulImprovements in Gangways for Car-Ferries and. the like, of which thefollowing is a specifica tion. The invention relates to improvements ina gangway for car ferries and the like as described in the presentspecification and illustrated. in the accompanying drawings that formpart of the same.

The invention consists essentially in the novel construction andarrangement of parts whereby a gateway is provided on its outer sidewith rails corresponding to the rails on the floor of the ferry and isadapted to be thrown backwardly on said floor, its rails thus forming acontinuity of the track line on said floor.

The objects of the invention are to produce a device which will act as abarrier against the inrush of water consequent upon the turning of theferry and which can be readily converted into a part of the trackway andgenerally to simplify the construction of ferries and the like.

In the drawings, Figure 1 is a plan view showing the gate thrown backand forming part of the track line. Fig. 2 is an end elevation of thestructure. Fig. 3 is a side elevation showing the gate in the raisedposition.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings, 1 represents the ferry having the tapered end2 having cut therein the opening 3 adapted to be engaged by a suitableplatform from the dock, said platform having attached thereto anchorsadapted to engage the dogs 4 on the ferry, the platform fitting snuglyinto the opening 3 preventing any lateral movement of the ferry whilethe anchors prevent any movement to or away from the dock.

5 is the deck of the ferry being composed of overlapping metal plates 6as customary and having attached thereto to the chairs 7 such as areused ordinarily in railway construction and adapted to carry the rails8.

9 is a gate secured to the ferry by the hinges 10 and 11 and beingcomposed of a lower layer of overlapping metal plates 12 similar to theplates 6 and an upper facing of metal 13, the twolayers'being spaced bythe wooden blocks 14: the whole being of a thickness to correspond withthe height of the chairs 7.

15 are rails on the gate 9 corresponding to the rails 8 on the floor 5.

16 are rods at each end of the gate having their lower ends pivotallysecured in the sockets 17 a short distancebehind the gate 9, and theexternally threaded upper ends 18 adapted to be engagedby a collar 19,said collar having its lower end 20 correspondingly threaded internally,the upper end 21 of said collar having the oppositely running threadadapted to engage the rods 22, the said collar owing to its oppositelythreaded ends facilitating the shortening or lengthening of said bracesas when the collar is turned one way it draws the rods 22 toward the rod16 and when'turned in the opposite direction it forces the rods 22 awayfrom the rods 16.

23 is a portable wooden beam adapted to abut the inner side of the gatewhen in the up position and having therein the sockets 24 adapted toengage the ends of the rods 22, the said rods acting as a brace to keepthe gate in the raised position.

25 is a cable attached to the gate at its upper end and runningbackwardly over suitable pulleys 26 to a winding drum, the said cableand drum being for the purpose of raising or lowering the gate.

27 is a weight attached to the cable 25 to further facilitate theraising of the gate.

In the operation of this invention when it is desired to load the ferrywith cars the collar 19 is turned drawing the rods 22 toward-the rods 16and away from their sockets 24, the braces are thrown backwardly on thedeck and the portable beam 23 is thrown to one side, the drum is nextunwound allowing the gate 9 to fall inwardly, the inner ends of therails on the gate abutting the ends of the rails 8 on the deck, the carsare then run on to the ferry and the gate again raised to its verticalposition by means of the drum and weight, the beam 23 is placed againstthe said gate and the braces placed in position as explained, thusclosing in the deck and preventing any inflow of water and also p saiddeck and having correspondingrailson the outer side and adapted to swingin- Wardlyand means-for raising said gate;

2; In a gangWay for car ferries, a deck structure having plating andrails forming tracks on said plating, a gate hinged at its lower, endand having rails on the outer .fac'e thereof meeting the aforesaid railsand a cable and Weight with pulleys therefor for raising said gatel T v3. In a gangvvay for car ferries, a deck structure having plating trackson said plating, a gatehaving corresponding plating and an inner platingdistanced from the outer plating and rails on the l atter brought toahaving deck plating,

-- means for raising said and rails forming level of the deck rails bysaid distancing, and means for raismg said gate.

l. Ina gangway for car ferries, a deck structure having rails supportedby chairs and formingitracks, agate having a double Wall separated bydistance pieces and rails on the outer wall-meeting the aforesaid rails,gate, and means for buttre'ssing said gate in its upper position. 5, In,a gangway for car ferries, a deck structure having rails securedthereon, and, g hinged. tq the d ck }.w*

forming tracks, v v I i and havlng correspondlng ra ls on theouter side,means for ralsing said gate, a buttress 0n the inner side anda strut'adjustable as to length and bracing said buttress in position.
